Tarlatamab是靶向DLL3×CD3的双特异性T细胞衔接器(BiTE),2024年获美国FDA批准用于小细胞肺癌(SCLC),是当年获批的抗体新分子之一,获批依据是在经治SCLC中较标准治疗改善缓解率与无进展生存的II期数据,此后多项III期研究持续跟进[1][2][6]。这一瘤种对铂类化疗初始敏感但耐药极快、预后恶劣,PD-(L)1抑制剂与ADC带来的获益仍然有限[4]。安全性上CRS是主要顾虑,DeLLphi-300子研究显示,周期1改为6–8小时门诊监测后任意级别CRS约60%,与48小时住院监测(62%)相当,为更大规模应用提供了可行性依据[5]。
本次ESMO 2026主席专场的LBA3报告DeLLphi-305 III期结果:ES-SCLC患者经一线化疗+度伐利尤单抗诱导后,随机接受tarlatamab+度伐利尤单抗对比度伐利尤单抗单药维持治疗。Amgen于9月8日宣布研究在期中分析即达到OS终点;会上公布的数字为:OS 21.1 vs 12.7个月(HR 0.42),PFS 7.4 vs 1.9个月(HR 0.34),CRS发生率49.6%,≥3级仅0.4%。报告人为Jacob Sands,10月24日(周六)17:18,Hall 6。
相对已有认识,DeLLphi-305把tarlatamab的证据从经治后线人群[2][5]推进到一线维持阶段,并直接与PD-L1抑制剂联合,OS HR 0.42的幅度也使其成为主席专场三场报告之一。现场帖同时在谈的另一条线是与IMforte(阿替利珠单抗+鲁比克替丁维持,OS HR 0.73)的间接对照:发帖者明确表示跨试验比较不恰当,但tarlatamab组的OS获益在数值上明显更大;另有帖文提出tarlatamab可入脑而IMforte方案不能,此点属发帖者观点,会上未见相应数据,待确认。
局限在于目前仅有会议顶线数字,OS成熟度、后续治疗线、CNS疗效、生活质量与完整安全性谱均待全文披露;durvalumab单药组PFS仅1.9个月,联合组获益能否长期维持也需更长随访验证。

Ippokratis Korantzis, Medical Oncologist, MD, PhD@newsincancer CrozrX@CrozrX 引用@🚨🔥 ABSOLUTELY STUNNING! DeLLphi-305 at #ESMO26! @sands_jacob presents remarkable phase III results in ES-SCLC! 💥 Tarlatamab + durvalumab vs durvalumab maintenance 🔥 Median OS: 21.1 vs 12.7 months 🔥 HR 0.42 (95% CI 0.32–0.54), p<0.001 🔥 12-month OS: 79% vs 53% 58% reduction in the hazard of death! These are extraordinary results in a disease where meaningful survival advances have been so difficult to achieve. 👏 Congratulations and I welcome A new benchmark for ES-SCLC maintenance therapy #ESMOAmbassadors #ESMO26 #SCLC #LungCancer #DeLLphi305
